Is this a separate version (i.e a paid upgrade to the original version?) - I did start this, but thought the perf was super rough on Xbox One. If that’s been improved for Series X|S, then I’d give it another go.
Yes, it’s listed as observer redux on the store @ 25 quid.
They did do a cheaper upgrade offer (£5 or so) but only for a really short time and with little to no publicity for owners of the original so many missed out.
I’ll have more time to play it today, I doubt it is 4k 60 with ray tracing on, for the few mins I walked around after enabling ray tracing it was pretty smooth though.
The game was really sluggish when it launched but had several patches before the Ray Tracing patch to fix the framerate.
